How to convert Moment.js moment to unix timestamp

Question

I see a lot in the Moment.js documentation about getting a Moment from a Unix timestamp. However, I am trying to convert a Moment to a Unix timestamp, and I am not sure how to do that. This is how my moment looks:

const myMomentObject = moment(str_time, 'YYYY-MM-DD');

And I need to convert it to a Unix timestamp.

Answer 1

Call unix() on moment object. Reference .

moment('2020-12-12').unix()

Answer 2

Unix timestamp can be obtaineded with or without the moment library.

 //Moment const myMomentObject = moment('2021-10-16', 'YYYY-MM-DD'); console.log(myMomentObject.unix()); //Vanilla const d = new Date('2021.10.16'); console.log(d.getTime() / 1000);

Answer 3

To create a Unix timestamp (seconds since the Unix Epoch) from a moment, use the following,

 console.log(moment('2021-10-16').unix());

Since your date format follows the ISO_8601 format, ie YYYY-MM-DD you do not need to provide the input date format to the moment constructor.
